Safety Overview

NOTE: Proper planning and thorough preparation are critical for successful installation. This
chapter outlines basic requirements for the pre-installation phase.
Prior to starting the installation process, you must develop and launch an installer safety training
plan for initial, refresher, and ongoing safety training. Ensure that installers receive appropriate
initial and refresher training to meet their specific safety-related responsibilities. Installers should be
instructed in the following safety elements as well as any site-specific safety issues.
•
New duties for which the installer has not previously received training.
•
New processes and methodologies representing new risks that are introduced into the
installation environment.
•
Situations where previously unidentified risks are reported.
•
Hazard Communication (Employee Right to Know)
•
Lifting
•
Safe driving
•
Use of hand tools
•
Confined space
The installation supervisory team assumes responsibility for ensuring that installers are properly
trained, authorized, and continually qualified to perform their work. The team must also take
responsibility for the safety of their installers and to assure safe work methodologies. Installers must

Figure 6 - 4. Mounted GPR
The GPR module, as received from the contract manufacturer, should have the correct Network
LAN ID and CRC numbers already configured. The GPR, when installed for the first time, will start
operation in Install Mode. Install Mode is a temporary operation mode during which the GPR
initiates the first network synchronization, and performs auto-registration to Command Center. To be
able to sync to a network the GPR must have the same CRC number as that of the Network. During
auto-registration the GPR requests for operation and meter specific configurations from Command
Center. When the new configuration data is obtained, the GPR reconfigures itself, reboots, and then
changes operation to Normal Mode.
To start the GPR in Install Mode follow the procedure below.
1. Apply dielectric Grease Compound to the sensor cable connector and make the connection as
described in the interface section above. See Appendix A GPR Waterproofing for more
information.
2. Apply Di-Electric Grease Compound to the battery connector. See Appendix A GPR
Waterproofing for more information.
3. Install the sensor cable connector before the battery connector to avoid creating false counts.
4. Apply power to the module by making the battery connection.
5. Remove and discard the foam between battery and PCBA.
6. Observe the LED on the module for proper start up. Shortly after power is applied, the LED will
flash once every 5 seconds for 60 seconds to indicate to the installer that the module is in
Installation Mode and is operating normally. If an error is encountered, the LED will flash twice
per second to indicate there is error and continue flashing until power is disconnected.
7. If the module started operation correctly, mount the cover using the next 3 steps.
8. Arrange the GPR Pulse Input and Battery Interface cables as shown in Figure 6 - 5. The cables
must not interfere with or block the GPR antenna. Pull the wires over the connector as shown.

•





Installation Guide
By design the hardware counting channels are labeled A and B. In Command Center,
channels 1 and 2 are used.
•
Channel A = Command Center channel 2
•
Channel B = Command Center channel 1
•
Channel A. Optional volume input.
•
Channel B. Primary volume input.
•
Alarm. Alarm input.
•
Both channel A and B can support Form-A or Form-C type pulsers.
•
The alarm channel can support Form-A or Form-B type pulsers.
•
Minimum ON/OFF input pulse width is 50 mSec / 50 mSec.
•
Nominal switch bias voltage is 3.0V.
•
Nominal switch bias current is 30 uA.
NOTE: The billing or primary output on the pulser is to be connected to Channel B on the GPR.
NOTE: It is the responsibility of the user to make sure the output pulse meets the minimum pulse
ON/OFF time. This is usually a configurable parameter for electronic volume correctors.
NOTE: When both channels, A and B, are connected and used as volume inputs in an installation, it
is highly recommended that both channels are connected and configured for type Form-A at the
pulser side as well as the GPR side. If Form-C is used in a dual volume input configuration, the
battery life of the GPR is not guaranteed.
NOTE: The GPR should not be connected to any output that has power. It is a good practice to
measure the output of the pulser before installing to the GPR. Voltage above 6.0V can cause
damage to the GPR and will violate the intrinsic safety rating.
NOTE: If the battery is unplugged, do not connect the battery until the module is ready for operation
to start.

Installation in Hazardous
Locations
Information
The following information describes and limits what can be attached to the GPR in a Division 1
location per the UL certification.
1. GPR Entity Parameters:
•
Uo (Voc) = 6.3 V dc
•
Io (Isc) = 7.34 A
•
Po = 5.91 W
•
Co (Ca) = 207 uF
•
Lo (La) = 43 uH
2. The output current of the GPR is limited by a resistor such that the output voltage-current plot is
a straight line drawn between open-circuit voltage and short-circuit current.
3. Selected intrinsically safe equipment must be third party listed as intrinsically safe for the
application, and have intrinsically safe entity parameters conforming to Table B - 1 below.
Table B - 1. Conforming Safety Parameters
I.S Equipment
GPR
Ui (or V max)
6.3 V dc
Ii (or I max)
7.34 A
Pi (or P max)
or
5.91 W
Ci + Ccable
207 uF
Li + Lcable
43 uH
4. This associated apparatus may also be connected to simple apparatus as defined in Article 504.2
and installed and temperature classified in accordance with article 504.10(B) of the National
Electrical Code (ANSI/NFPA 70), or other local codes, as applicable. The GPRs described in
this guide qualify as simple apparatus for the purposes of intrinsic safety.
5. Capacitance and Inductance of the field wiring from the intrinsically safe equipment to the GPR
shall be calculated and must be included in the system calculation as shown in Table B - 1. Cable
capacitance, Ccable, plus intrinsically safe equipment capacitance, Ci must be less than the
marked capacitance, Ca (or Co), shown on any associated apparatus used. The same applies for
inductance (Lcable, Li and La or Lo, respectively). Where the cable capacitance and inductance
per foot are not known, the following values shall be used: Ccable=60pF/ft., Lcable= 0.2 uH/ft.
The total capacitance and inductance of each I.S. device and associated cable is to be added
together and cannot exceed the stated Co and Lo values.
